Frank B. Zoltowski (born 1957) is an Australian amateur astronomer and prolific discoverer of minor planets who lives in Woomera, South Australia. In 1998, he was awarded a "Gene Shoemaker NEO Grant" for improved near-Earth object searches.^[2][3]

Zoltowski conducts these searches from his home with a charge-coupled device camera.^[2] He is a prolific discoverer of asteroids. He authored CCDTRACK, a computer program that auto-guides electronically controlled telescopes by tracking a user-selected celestial object.

He is mentioned in NASA's asteroid tracking database as an observer for asteroid (285263) 1998 QE2.^[4] Astronomers at the Minor Planet Center used Zoltowski's work to work out an estimated approach distance for (137108) 1999 AN10 of 56,500 kilometers, and a closest approach date of Aug 7, 2027.^[5] It was thought to potentially crash into Earth.^[6][7][8]

The main-belt asteroid 18292 Zoltowski, discovered at the George R. Agassiz Station of the Harvard College Observatory in 1977, was named in his honor.^[3] The naming citation was published on 9 May 2001 (M.P.C. 42676).^[9]

Frank Zoltowski is credited by the Minor Planet Center for the discovery of 228 numbered minor planets between 1997 and 2003.^[1]
